Calculating the Torque of Your Diesel Engine

Torque is the driving force of an engine which is responsible for rotating the wheels and twisting the whole mechanism from crankshaft to the movement of the wheel on the road. When the process of combustion takes place in the engine, the pressure is created against the pistons to produce the power.

This power is used to oppose the force and push them back. This force is then transferred via the connecting rods to the crankshaft. You can calculate the torque of the engine while concentrating over the cycle of the engine.

You can seek professional help from puredieselpower for enhancing and calculating your diesel engine’s exact torque. For getting the exact value of torque, you need to find the variable of torque.

Variables of Torque

For any engine, there are only three main variables of torque that is the force at specific RPM, constant torque, and distance. The force of your engine is also known as its horsepower. You can find the torque of your engine on its specific revolution.

When the torque is calculated on maximum RPM then it is known as full motor torque. This torque could be found at the engine specification table. The torque generation is directly proportional to the length of stroke, the longer the stroke, the more torque it will produce.

Due to this reason, the torque of the diesel engine is more as compared to petrol engine as they have longer strokes which are based on the air compression in the cylinder. The unit of torque is lb-ft or pound-feet.

Calculating Torque

Calculating engine’s torque is not difficult, there are a few multiplications of force and distance from the center of the crankshaft. The distance is the variable of torque, so if you increase the distance of crankshaft then it will result in more torques. You can use powerstroke performance upgrades to increase torque of your engine. For calculating the torque of an engine you can use formula

Torque = (Force x 5252) / Engine’s RPM


T= (HP x 5252) /RPM

Here T is torque of the engine, HP is horsepower of an engine, 5252 is the constant and RPM is the revolution of engine per minute.

Torque is the driving force of your vehicle. It is the factor which helps your vehicle to climb hills so easily. Here is a useful reference on getting more out your engine.
